Review on Efficient Networking: VCE 25-Pack Cat6 RJ45 90-Degree Keystone Jack Insert, Black Ethernet UTP Cat6 Keystone Jacks (UL Listed) by Robert Oner

Home Depot sells them for $5 each, making them very good deals. I only had one bad keystone out of 25 installed. (I'm glad I checked each before zipping everything up). They are no easier or more difficult to install than any other brand and they work as expected. I read in a review that the colors don't match, but that doesn't apply to the batch I received. The build quality is good, especially considering the low price. I'd recommend testing each connection before closing anything, but at the price of 1 in 25 it's still great value.
